LIMITED, 0F WESTMINSIER, ENGLAND GLAZED FRAME Application led August 7;'1931, SerialJ No. 555,668, and in Great Britain September 18, 1930@V Theinvention relates-to that kind of glazed necessary for such frames to bemade without solder and with the metal in Contact with the sheets ofglass which are thick', not only around all the edges of each pane, butalso against the two facesthereof. Such a construction renders theglazed frame lnore rigid and waterproof and improves the appearancethereof. s

The object of the present inventionis to form such a frame in a cheapand efficient manner which will render the saine lireproof rigid andwaterproof. Y f According to the present invention the sash bars areV ofI shape in cross section with straight flanges and all the grooves inthe sides of the bars lit the glass tobe used therewith around the edgesof each pane and' on both faces thereof. One set of sash barsvisnarrower than the other set due to its having thinner flanges, althoughthe grooves for the glass are the same in both sets. As the grooves arethe same in both sets of bars it follows that the flanges onthe widerbars are thicker than the anges on the narrower bars. The wider bars arecut away to iit the narrower bars and to allow these latter to be passedtherethrough7 and the Portion cut away partly enters into the thickervside lianges of the wider ba-r.

The metal frames for use with such sash bars are of channel shape andhave three flat sides at right angles to each other which fit two sidesof the sash bars and the ends thereof. The channels may be turnedinwards along their open side for a short distance and the sash bars aregrooved through their anges and the flanges oi the wider bars are partlycut away so that the sash bars may be slid into position in the framefrom an open end of one side of the ramememberszor'may' be' forced into:position by causing the sides of the channel. to spring open.

lInstead. off employing two sets. of I shaped. bars; as. abovedescribed, one set. of the bars, the narrower' one,. may be I shaped.with straight: lianges and the other and wider I bars may beha-te curvedflanges instead. of straight flanges'. These curved flanges; are: curvedtowards each other and the webs and the edgesaof these curved flangesaree-ut away to fit to allowthe narrower I shaped :barsI to be passedtherethrough. When employ-v ing wider bars having curved flanges thetwo. outer curves t at their edges against theV fla-t outside edgesofthenarrower sash bars.

The channel Ashaped framey may bey made up in4 any suitable manner.

The `channel' shaped frame may be formed by cutting V shaped pieces outof the channel which will allow adjoining parts to be. bent .up at rightangles to, each other. In som-e cases one side and parts. of two othersides are thus bent up outof a single piece of channel. A second piece.of channel is similarly bent up and the :two pieces are connected.together by means of linerswhich accurately tigt into the open ends ofthe part sides.

The invention is illustrated in thel accompanying drawings in which Fig.l is; an end elevation of one of the wider sash bars and Fig. 2 is anend elevation of one. of the narrower sash bars.

Fig. 8 is a similar view to Fig. 7 showing a narrower' sash bar.

Fig. 9 is a front elevation showing one construction of a frame partlybroken away and with sash bars inserted therein.

Fig. 10 is a side elevation of part of the channel employed to make theframe shown in Fig. 9.

Fig. 11 is a section through part of the frame showing one of the widersash bars in position therein.

Fig. 12 is a section through part of the frame showing a narrower sashbar inserted therein.

Fig. 13 is a section of the frame on the line 13-13 of Fig. 9 with aconnecting liner therein.

Fig. 14 is a side elevation of the wider sash bar shown in Fig. 6.

As shown in Figs. 1 and 2 the sash bars are of I shape in cros'ssection. The bar shown in Fig. 1 has a web 1 and side flanges 2, 2. rlhesash bar shown in Fig. 2 has a web 8 and side flanges 4, 4. It will benoticed that the flanges 2, 2 are thicker than the flanges 4, 4 and thatthe grooves 5, 5 in the sides of the bars, to receive the glass, areequal in width.

As seen in Fig. 3 the wider sash bar 1, 2 is cut away at 6 to allow thenarrower sash bar 3, 4 to pass therethrough. It will be noticed thatparts of the flanges 2, 2 have been cut away.

Fig. 4 shows a narrower sash bar 3, 4 passed through a wider sash bar 1,2.

A modified form of the wider sash bar is shown in section in Fig. 6, inwhich the flanges 7, 7 are curved, that is to say bent towards eachother and are connected to a web 8. The edges of the flanges 7, 7 andpart of the web 8 are cut away, as shown in Fig. 14, with an aperture 6similar in shape to that shown in Fig. 3 to allow a narrower sash bar tobe passed therethrough.

Fig. 5 is an end elevation of one member of the preferred form of frameemployed to carry the sash bars. It consists of three sides 9, 10, 10 atright angles to each other and fitting in its interior the outside facesof the thinner flanges 4, 4 of the narrower sash bars, and also fittingacross the ends thereof. rlhe sides 10, 10 are turned inwards towardseach other at 11, 11.

The sash bars as shown in Figs. 7 and 8 are grooved at 12, 12 to slideover the inwardly turned parts 11 of the frame. As the wider sash bar 1,2 will not lit within the frame a portion of each flange 2 is cut awayat 13 (Fig. 7) to reduce the width of the end to that of a narrow sashbar 3, 4. In some cases the sash bars may he cut away with inclines 14as shown in Figs. 11 and 12 so that the reduced ends may be insertedbetween the inwardly turned parts 11. When pressure is applied to theframe member 9, 10 the reduced end will open out the channel and allowthe projections 11 to spring into position in the grooves 12.

The frame shown in Fig. 9 is made from two pieces of channel havingsections shown in Fig.A 5, which pieces are partly cut away at 15, asshown in Fig. 10, to enable the portions of the channel to be bent atright angles to each other to form the mitres 16 of the frame. Two ofsuch pieces are thus bent up and are placed with their straight ends 17in Contact with each other as seen in Fig. 9.

Prior to placing the two ends 17 together he liner 18 is inserted in oneof the ends and the other end is passed over the exterior of the liner.The two liners 18 keep the two portions of the frame in alignment.

Such frames with their sash bars are built into hard wood partitions andsashes which retain the two parts of the frames rigidly together andprevent the frame twisting. The partitions and sashes are not shown asthey form no part of the present invention.

Some of the sash bars may be as shown in Figs. 7 and S and may be slidinto the vertical side members of the frame before the two parts thereofare connected together. rlfhe sash bars with tapered ends shown in Figs.11 and 1.2 are primarily intended to be jumped into the horizontalmembers of the frame but they may also be slid into the open endsthereof. Before connecting the two parts of the frame together thenarrower sash bars are inserted through the apertures 6 in the widersash bars and the sheets of glass are also inserted.

1n the construction shown in Fig. 9 the horizontal sash bars are thewider ones, such as shown in Figs. 6, 7, 11 and 14, and they are slidinto the open ends of the vertical members of the frame. The narrowervertical sash bars are as shown in Fig. 12 so that they may be umpedinto the horizontal members of the frame.

It will be readily understood that narrower sash bars, such as shown inFigs. 8 and 12, may be slid into the vertical side members of the frameand that wider sash bars, as shown in Fig. 11, may be used ver ticallyand may be jumped into the horizontal members of the frame and such aconstruction is therefore not shown.

W hat we claim as our invention is 1. An improved glazed frame havingtwo sets of metal sash bars both of I section, both sash bars 1navingchannels in the sides of similar width, one set of sash bars havingthicker flanges than the other set, the sash bars having the thickerflanges being formed with apertures through which are passed the sashbars having the thinner flanges, a frame of channel section havinginwardly turned parts along its open side and grooves in the set, thesash bars having the thicker flanges being cut away to accurately fitthe sash bars having the thinner flanges, these latter bars being passedthrough said apertures, and a channel shaped frame to receive the endsof both sets of sash bars within the channel, substantially as setforth.
